The most obvious parallel with what McDaniel supporters are claiming comes from a case involving Brown, who serves as the Noxubee County Democratic Party chairman. Brown was found guilty of racial discrimination under the Voting Rights Act because he challenged white voters he said were Republicans and tried to prevent them from voting in the Democratic primary. The reason, in a nutshell, is that Brown targeted white voters because there was no other means of determining whether a voter supported Democrats or Republicans.

So how do McDaniel supporters know that Cochran supporters are targeting Democratic voters only? Well, there's the fact that Warren says he's a Democrat, and it could follow therefore that he's recruiting Democrats. Of course, the rather unspoken part is that Warren's efforts are all in black communities. Since a majority of black voters support Democratic nominees, it could follow therefore that Warren is recruiting Democrats.

However, that leads to a pretty serious problem for McDaniel supporters: the only real identifying factor they have is race.

That said, it should be pointed out that Mississippi Democratic Party Chairman Rickey Cole was the first to raise the issue of MS Code 23–15–575 being violated by Warren and the pro-Cochran PAC, making the argument Monday in a Facebook message to a Wall Street Journal reporter.

But here's the rub: that statute is unenforceable.

The Mississippi Democratic Party filed a federal lawsuit in 2006 trying to prevent Republicans from voting in Democratic primaries. The lawsuit was conceived and argued by Cleveland attorney Ellis Turnage, who feared that a number of Republicans might vote in the Democratic primary to help challenger Chuck Espy defeat U.S. Rep. Bennie Thompson.

U.S. District Judge Allen Pepper ruled in Turnage's favor, saying that Mississippi's closed primary system and lack of party registration infringed on the right of political parties to keep their primaries closed to members only. To rectify this problem, Pepper in 2007 ordered that the Legislature change its election laws, enforce party registration and require voter identification proving party affiliation be presented at the polls.

That ruling caused the biggest cluster you've ever seen. The Mississippi Democratic Party, Mississippi Republican Party, NAACP, then-Gov. Haley Barbour, Secretary of State Delbert Hosemann and Attorney General Jim Hood all appealed the ruling. In 2008, a three-judge panel for the U.S. 5th Circuit Court of Appeals overturned Pepper's ruling.

"We will put the parties out of their litigation misery," Judge Edith Jones wrote in the opinion.

The reason, however, was that the panel ruled Turnage and the Mississippi Democratic Party had no basis to bring the case because they had not tried to prevent non-Democrats from voting in a primary and been stopped doing so.

There's another reason this law is unenforceable as written. State statute (23–15–571) outlines the reasons for challenging a vote. They include:

That he is not a registered voter in the precinct;That he is not the registered voter under whose name he has applied to vote;

That he has already voted in the election;

That he is not a resident in the precinct where he is registered;

That he has illegally registered to vote;

That he has removed his ballot from the polling place; or

That he is otherwise disqualified by law.

What you don't see on this list is anything dealing with party affiliation.

So while McDaniel supporters are in a tizzy over Cochran supporters seeking votes in black communities, Mississippi Conservative PAC appears to be doing nothing wrong. Unless McDaniel supporters want to invite race into the discussion, they should move on to another issue. This one is a loser for them.
